Istivin : City of Shadows.
Pact of Greyhawk
The Pact of Greyhawk was the peace treaty that ended the escalating conflicts that began in 569 CY. Signed and negotiated in the City of Greyhawk, the Pact was a diplomatic victory that brought more nation-states and key players to the table than at any previous time in history and greatly increased Greyhawk’s prestige and power.
Under the Pact, the borders of every nation on the continent were fixed, and any country violating another’s sovereignty would come under attack from the other countries. Pomarj did not sign the Pact, and continued harassing its neighbors. The giants who invaded Sterich and Geoff during the War did not sign, though Sterich was liberated in 575 CY .
Ironically, because the universal peace treaty was signed in Greyhawk, the entire conflict across the Flanaess became known as the Greyhawk Wars.
